Knife gate valve is with movement direction and perpendicular to the direction of flow gate opening and closing valves, cutting off media function, is often used in uncontrolled fluid pipes, based on field control needs, has been equipped with electric or pneumatic actuators to automate valve operation.
Knife type gate is with movement direction and fluid direction phase vertical of gate Board as opening and closing pieces of gate, has cut media of function, makes valve close not by media blocked, cut media of effect good, often was for some to control of fluid pipeline in the, widely application Yu mining, and food, and paper, and medicine, and oil, and chemical, field, traditional of knife type gate is manual form of, but according to site control of needs, now has widely equipped with electric or pneumatic implementation device to achieved valve of Automation operation.
Knife-type valve 7 points should be paid attention during the installation details
Knife-type valve valve assembly maintenance simple, reasonable seal structure, seal easy to replace, with practical easy movement, open, free, flexible and reliable. But in order to prevent adverse effects during the installation process, do the following points should be noted:
1, pay attention to keep the valve Chamber and sealing and other parts clean, avoid with dirt or sand attached to be installed;
2, check whether the connection bolt screw down to ensure the pipeline valve off under the impact of the media;
3, check the valve packing area is pressed, to ensure that the packing and sealing of the gate open flexibility;

4, check valve, connection size and medium flows in order to ensure that consistent with the requirement of valve piping;
5, set aside the valve drive space necessary to facilitate operations;
6, using the automated driving device, check the wiring is connected according to the circuit diagram for drives;
7, need regular maintenance the valve to avoid valve collision and compression to ensure valve sealing.
